2 cal pro E X P A N S I O N V E S S E L S - PED 97/23/CE DRAWING/ ADVANTAGES OF CLOSED EXPANSION VESSELS The chart displayed on the back page of this information sheet shows how the volume or water increases due to a rise in temperature. In practice, water cannot be compressed and therefore any increase in water volume must be accomodated in an expansion vessel designed and sized for that purpose. The ZILMET closed expansion vessel, which uses a synthetic rubber membrane, has many advantages over open vented systems. Problems associated with open expansion tanks include the following: F I X E D M E M B R A N E E X P A N S I O N V E S S E L S evaporation of water necessitating fresh water top up; corrosion and fouling of system components due to fresh water introduction and exposure to atmosphere; greater heat losses due to conduction and water evaporarion; longer installation time (higher cost) due to additional components, pipework, insulation and access diffuculties; air venting problems due to poor siting and sizing of feed and expansion pipe connections. The expansion vessel with fixed membrane has been very successful due to the fact that the possibility of contact between water and air (gas) can be completely avoided.
